In sum aqueous inorganic building close alkali-resistant primer adhesive force is strong, hardness is high, closed performance is good, waterproof, alkali resistant, solidification basal plane and the finish paint compatibility good, without VOC, without harmful substances such as formaldehyde, stupid, heavy metals, technique, construction are simply, with low cost.
Detailed description of the invention
The invention will be further described below:
The present invention comprises the following steps:
(1) with parts by weight, adding the water of 50 parts, the inorganic dispersant of 0.5 part, the defoamer of 0.2 part, 1.5 parts of coalescents, the antifreezing agent of 0.5 part successively in blender, speed is 300 revs/min, and mixing time is stirred for 15 minutes；
(2) adding the Ludox of 22 parts, mixing speed is 300 revs/min, and mixing time is stirred for 15 minutes；
(3) entering the organic silican polymer emulsion of 25 parts, mixing speed is 300 revs/min, stirs and is stirred for 15 minutes；
(4) adding the defoamer of 0.2 part, speed 300 revs/min, mixing time is within 15 minutes, stir to obtain inorganic priming paint.
Further, described Ludox mean diameter to be 7-10nm, described organic silicon emulsion the be silicone acrylic emulsion of model 996KD, described inorganic dispersant are DISPERSOGENSPS silicate paint dispersant, described defoamer model is 367；Described antifreezing agent is ethylene glycol.
The present invention adopts Ludox, modifiies the inorganic building priming paint making one-component with organic silicon emulsion, and infiltration solidification base material is compatible with the finish paint of various compositions, keeps the chronicity of decorative effect.Good stability, longer-term storage does not precipitate and is divided into, and is not added with any preservative without rotten.Overcome tradition aqueous priming paint not alkali resistant, not water-fast, poor adhesive force, easily shortcoming putrid and deteriorated, poisonous and hazardous.The Ludox adopted, is nano grade inorganic material, may penetrate into basal plane, combines together with basal plane, form good adhesive force after solidification.Adopt silicone acrylic emulsion, without the Organic substance such as formaldehyde, benzene, be novel environment friendly emulsion.Blended with Ludox, improve the hardness of film, waterproof effect and breathability.Priming paint is nonpoisonous and tasteless with it, infiltration solidification power strong for aqueous inorganic building, alkali resistant, waterproof, easily storages, fast drying, construction are simple and convenient, has the excellent compatibility with other finish paints.Therefore, possesses wide market prospect.
The ultimate principle of the present invention is as follows: Ludox is with the aqueous dispersions of silica sol for film forming matter, its membrane formation mechanism is, when Ludox dries out, monomeric silicic acid is polymerized gradually, along with moisture evaporates, colloid molecules increases, and can form firmly Si-O-Si keyboard between SiO2 particle, then form silica chain network structure, become continuous film.Owing in Ludox, the salt content of solubility is low, thus make film have good resistance to water, and Ludox is cheap, has been widely used as research and the application of inorganic coating.Due to pore effect, independent Ludox is as film forming matter, it is easy to occur that coating adhesion is poor, cracking or even the phenomenon such as efflorescence, and the present invention adopts organic silicon emulsion to modifiy, and overcomes the shortcoming individually using Ludox coating cracking.The use of inorganic dispersant overcomes the cohesion between power inorganic molecule, ensures the not stratified precipitation of long term storage.Add antifreezing agent guarantee not freeze at low temperatures, do not affect normal construction, its fast filming can also be promoted simultaneously.Because totally coordinating alkalescence, the nutrient substance needed without Institute of Micro-biology again, be not suitable for microbial survival, growth, so will not be putrid and deteriorated in storage.
In sum, the inorganic building priming paint of novel environment friendly provided by the invention is with silicone acrylic emulsion modified silicasol for main film forming substance, avoid Ludox independent film forming and pore effect occurs, thus improving resistance to water and the filming performance of priming paint, and keep priming paint ultimate cost cheap, modifiied by a small amount of organic silicon emulsion simultaneously, improve filming performance and the early stage resistance to water of priming paint further, make the priming paint of final preparation keep ultrahigh hardness, good breathability；It is sterically hindered that the addition of inorganic dispersant increases SiO2 aggregate surface, it is possible to effectively prevent coating store or thermal histories in further condensation and gel, substantially prolongs effective storage time of coating；By adding silicone acrylic emulsion, effectively raise the compatibility that organic-inorganic is biphase, avoid the Organic substance anti-thick initiated gel of breakdown of emulsion in storage process, make organic binder and inorganic filming substance form effective mutual network structure of interting, further increase coating to the adhesive force of ground, water proofing property and breathability.
The performance of the present invention such as following table:
| Project | Index |
| State in a reservoir | Without caking, uniform state after stirring |
| Application property | Twice are accessible |
